Kinin cascade
From WikiLectures
The kinin cascade is the fourth important plasma cascade system, next to the coagulation, fibrinolytic and complement cascades. Its main end product is bradykinin, a substance with a number of physiological effects, which is mainly used in inflammation, edemas, and pain [1].
Bradykinin[edit | edit source]
Bradykinin is a nonapeptide with powerful biological activity that:
- causes vasodilatation,
- increases vascular permeability,
- causes hypotension,
- stimulates nociceptors, participates in pain perception,
- induces smooth muscle contraction in a number of locations,
- activates phospholipase A2 and cellular metabolism arachidonic acids.
Kinin Cascade Proteins[edit | edit source]
Four protein components are involved in the formation of bradykinin, which are synthesized in the liver:
- coagulation factor XII (Hageman factor),
- coagulation factor XI,
- prekallikrein,
- high molecular weight kininogen.
